1 UNDER 385 Two-component epoxy primer UNDER 385 H 6985 PLAST 825 EXTRA 745 RELATED PRODUCTS Epoxy primer Hardener Plastic adhesion increasing agent Filler Dye PROPERTIES Fast-drying epoxy primer Very good adhesion to metal elements and most plastics, except for PP, PE, PTFE (Teflon) and mixtures thereof Superb anticorrosive resistance Good insulating properties Can be applied wet on wet

2 UNDER 385 SUBSTRATES Old paint coatings, including thermoplastic paints Degrease, dry sand P220 P360. Polyester putties Dry sand, for final sanding P240 P320. Steel Aluminium Galvanised steel Stainless steel Clean steel surfaces until reaching Sa 2/2 (wet blasting) or St3 (manual cleaning or using a power tool) in accordance with the PN-ISO standard; the surface after the treatment must be free from oil, grease, dust, loose old paint coating, mill scale, rust and foreign contaminants; the surface should exhibit the gloss of the metal substrate. Degrease, dry sand P280 P360 or mat with an abrasive needled cloth, degrease again. Degrease, mat with a fine abrasive needled cloth, degrease again. Degrease. Polyester laminates Degrease, dry sand P280. Plastics, except for PP, PE, PTFE and mixtures thereof PP plastic and mixtures thereof Degrease with PLAST 85 degreaser, mat with a needled cloth, degrease again. Degrease with PLAST 85 degreaser, mat with a needled cloth, degrease again. Apply the PLAST 825 or apply the PLAST 705 adhesion increasing agent.

If the filler is to be applied after 2 hours, first sand the layer of UNDER 385. Apply the Glaze or Soft Light filler at least.5 h after applying SPECTRAL UNDER 385 (in layer / 20 C). RECOATING UNDER 385 Number of UNDER 385 layers Drying time for UNDER min / 20 C NOTE: The next system layers can be applied in 2 hours without sanding. If the next coat is to be applied after 2 hours, first sand the layer of UNDER 385. DRYING TIME Time to sand 20 C 60 C 3 hours 45 min. CAUTION: Drying times apply to the temperatures of the individual elements. DRYING WITH AN INFRARED RADIATOR Distance Follow the recommendations of the equipment manufacturer. Time depending on the type and power of the lamp 0 20 min. CAUTION: Use the radiator no sooner than 0 min. after applying the last layer. Page 3/5

4 UNDER 385 SANDING Dry sanding P360 P500 Wet sanding P600 P000 PLAST 825 PLASTIC ADHESION INCREASING AGENT In order to increase the adhesion of the paint to plastic elements (especially made of PP and its mixtures), add PLAST 825 at 30% (by volume) of Component A. EXTRA 745 FILLER DYE A special additive to increase the hiding power in black acrylic fillers; when used at specific mixing ratios, the product gives grades of grey. Maximum quantity: 3% by weight. Overdosing the EXTRA 745 additive may reduce sandability of the filler and result in loss of adhesion. EQUIPMENT CLEANING Epoxy thinner. STORAGE CONDITIONS Store in a dry and cool room, away from sources of fire and heat. Avoid direct exposure to sunlight.
